In this age of multiple devices and ways to reach people, I find it curious how my friends have attached themselves to one preferred method over another. If you want to reach Kristin - text is a 50/50 shot but Facebook will guarantee a response. My friend Sara on the other hand is a text junkie, I know that will warrant a response much quicker than a social network ping. My husband loves his blackberry so he'll respond quicker to an email, even more so than a phone call for some reason, perhaps I should take issue with that. And finally, my friend Amy is one of the last few people I know that will respond to a phone call with a phone call back the same day.I don't have this written down anywhere. I just know. After trial and error and seeing where they spend their time and whether they do or don't respond to one method, I've sorted it out in my head. You should do the same with your audience. Find out where people are talking about you, where you get the greatest response when you put out a message and be there. Don't build an iPhone app if your audience is all on Blackberry or hasn't made the smartphone transition. Don't put a lot of effort into one social network just because you've heard other people using it. Know your audience, know how they like to communicate. Figure this out and you are one step closer to getting them to listen.
